ATTINY20-XU

Overview

The ATTINY20-XU is an 8-bit AVR microcontroller featuring a compact enhanced RISC architecture. It integrates 2KB of in-system programmable Flash memory, 128 bytes of SRAM, and 128 bytes of EEPROM. The device operates at a maximum clock frequency of 12MHz and supports a supply voltage range of 1.8V to 5.5V. It is housed in a 14-pin TSSOP package.

Feature Summary

• AVR enhanced RISC core delivering high efficiency with single-cycle instruction execution
• Low-power CMOS technology optimized for energy conservation
• Integrated non-volatile memory including Flash, SRAM, and EEPROM
• Wide operating voltage range suitable for diverse power environments

Applications

• Touch sensing applications such as buttons and sliders
• Consumer electronics devices
• Industrial control systems
• Automotive control panels

Procurement Notes

Verify the specific suffix 'XU' against official Microchip documentation to confirm the 14-TSSOP package and 12MHz speed rating. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer part number with current datasheets to validate availability and pinout configurations before procurement.

Selection Notes

Select this component when a balance of moderate code capacity and low power consumption is required. The 12MHz speed limit suits applications not demanding high-frequency processing. The wide voltage range allows flexibility in power supply design. Consider the 14-pin package size relative to board space constraints during the selection process.

Part Context

This device belongs to the ATtiny series of microcontrollers produced by Atmel, now part of Microchip Technology. The series is known for picoPower technology and is designed for cost-sensitive industrial and consumer markets. The ATtiny20 variant specifically offers 2KB of Flash, positioning it between smaller 1KB models and larger 4KB counterparts in terms of storage capacity.

Replacement Considerations

Check for direct substitutes within the ATtiny family, such as the ATtiny20-VU or ATtiny20-SSU, which may share identical functionality but differ in package type or temperature grade. Verify that any replacement maintains the same pinout and electrical specifications to ensure compatibility.
